4 Rigging & Unpacking Unit should not be removed from protective packaging until reaching final location. The 38LB Series should be handled and installed upright. Inspect the unit for shipping damage and file claim with transport agency if necessary. Confirm the nameplate voltage to ensure that it matches available power supply. Consult building and electrical codes as required in your area. Location Unit should be installed outdoors. Do not restrict service, wiring and piping areas. Also avoid positioning unit in manner restriction airflow or in areas where water will pour directly onto unit. Minimum recommended clearance space is shown in figure 1 to 4. Fig 1 Fig 2 Fig 3 Fig 4-4 -

5 Configuration Unit is shipped from factory in vertical discharge configuration as standard. However, converting to horizontal discharge as shown is simply effected without extra fittings or metal sheet work. To modify into horizontal discharge mode : 1. Ensure all electrical supply to the unit is disconnected and then loosen top and fan discharge panels by removing screws. 2. Release wires tie on fan motor wires in control box and ease wires out of hole for extra length for interchanging panels. 3. Assemble top panel on front of unit and secure with screws. 4. Final assembles fan discharge panel. Pull fans motor wires taut and retie extra length in control box. 5. Check fan for free rotation and observe that wiring has not been damaged or improperly strained.

6 Piping Connections / Piping Refer to Physical Data Table for correct piping sizes. The length of refrigerant pipe depends on the unit placement and building structure attempt to run pipes as CONNECTION TO INDOOR PIPING (Flare) CONNECTION TO INDOOR PIPING (Brazing) SHUT-OFF PORT FACTORY-BRAZED TO CONDENSING UNIT SHUT-OFF PORT FACTORY-BRAZED TO CONDENSING UNIT SERVICE PORT (SCHRAEDER) SERVICE PORT (SCHRAEDER) Service Valve (Flare) Service Valve (Blazing) 1. Refrigerant tubing between sections may be made using accessory tubing packages or field-supplied tubing of refrigerant grade, correct size and condition. 2. Refrigerant suction tube must be insulated with closed-cell foam type insulation with a minimum wall thickness of 3/8 in. Failure to properly insulate refrigerant tubes adequately will degrade system performance and efficiency as well as permitting moisture or frost to form on the tubing surfaces during operation. 3. Run refrigerant tubes as directly as possible, avoiding unnecessary turns and bends. 4. If tube bending is necessary, use only copper cutter to cut the copper tube and shape tube with a tube bender so that the tube ends coincide with flare connections. 5. Carefully remove the flare nut fitting from indoor and outdoor sections tubing. 6. Thoroughly clean all tubing connection points to prevent foreign matter from entering the refrigerant circuit. 7. Thread the 2 fittings by hand, making sure the threads fit smoothly and the flare seats evenly against the union. 8. Tighten the 2 fittings securely. 9. Connect piping to the indoor and outdoor section. 10. Evacuate the system at lower 500-micron for at least 30 minutes. 11. Suspend refrigerant tubes so they do not damage insulation on liquid and vapor tubes and do not transmit vibration to structure. Also, when passing refrigerant tubes through walls, seal opening so vibration is not transmitted to structure. Leave some slack in refrigerant tubes between structure and units to absorb vibration. 12. After evacuating the system, turn on both valves at the condensing unit to flow the refrigerant into the system. Outdoor unit contains holding refrigerant charge to operate split system

7 Maintenance Warning! To avoid the possibility of electric shock, before performing any cleaning and maintenance operations always turn off power to the system. If the indoor unit is on a separate switch, be sure it is also disconnected. Ensure that tubing is cool. Beware of rotating fan and energized electrical components. Cleaning coil : Ensure power to unit is disconnected. Wire grilles may be removed simply be lifting grilles upwards so that grille legs clear holes in base pan and then pulling them towards you (Fig. 4). Clean coil with water from ordinary hose at a pressure high enough to clean efficiently. Coils are double row and may be separated carefully and sufficiently be loosening screws at one end of the coil so that dirt may be flushed out towards the outside of both coils. Avoid splashing mud on coil or water onto fan motor. Condensing fan adjustment : The fan should be adjusted by loosening the set screws and moving the fan blade up or down. The final position of the fan relative to the louvers should be as shown in Fig. 5. Condenser fan removal : Shut off power to unit. Open control box cover and remove fan motor wire leads from attached components. Remove fan deck and then the 3 mounting nuts between fan bracket and deck. Remove 3 nuts between motor bracket and motor

10 Attention before operating 1. Please read this installation manual carefully. It contains further important instructions. 2. Do not anything block the air outlet and air inlet of the condensing unit. The refrigeration system may be broken down. 3. Due to temperature of outlet air is higher around degree C; it may be having an effect on environments especially tree, plant, or shrub etc. 4. Make sure that outlet air is moved out from installation area. It must not be return to air inlet. Do not be store until temperature above 42 degree C. The compressor or refrigeration system may be damaged. 5. For safety first, it should be turned off the breaker if the air conditioner does not be used for a long time. 6. If the condensing unit is installed on the ground, make sure that the location is not liable to flooding. 7. After a long use, check the unit fixing for damage. 8. Before cleaning, be sure to stop the operation and turn off the breaker. (As the fan is rotating at high speed, cleaning during operation may cause injury) 9. Do not place a vessel containing water or any object on the condensing unit and do not stand or sit on the condensing unit. 10. The condensing unit should not be installed where normal operation sounds may be objectionable. On either rooftop or ground level installations. Rubber padding can be applied between the base rails and their supports to lesson any transmission of vibration. 11. The fan of condensing unit is the propeller type. It is not suitable for use with duct work. 12. Make sure that the surrounding atmosphere does not contain noxious or dangerous substances such as oil vapors etc. Before inform our call center or inspect the air-conditioner, please check as following Case of Air-conditioner does not work, Disconnect the electrical? Turn off the breaker? Fuse is broken? Low level of the battery show on remote control? The timer function is set on remote control? Case of air-conditioner work but it can not cooling, Fan-coil is unclean? Open the door or the window? Pre-Filter is unclean? The position of louver is unsuitable? Low speed on fan-coil unit? The temperature setting is unsuitable set on remote control? / Carrier (Thailand) Ltd th.fl, 1858/63-74 Bangna-Trad Road Km. 4.5 Bangna Bangkok Tel Fax Carrier reserves the right to make changes in specifications 38LB/38LF_EN_11/2015
